Acid Corrosion Inhibition of Copper by Mangrove Tannin
Research Output | Dar Al-hikmah Library | IIUM Only

Purpose – The purpose of this paper is to evaluate the corrosion inhibition potential of mangrove (Rhizopora apiculata) tannin in hydrochloric acid medium on copper with the view of developing a natural corrosion inhibitor. Design/methodology/approach – The mangrove tannin was extracted from the mangrove bark and its anticorrosion potential was

Damage Mechanics Model for Solder/intermetallics Interface Fracture Process in Solder Joints
Research Output | Dar Al-hikmah Library | IIUM Only

The relatively brittle solder/IMC interface fracture process in reflowed solder joints is examined using finite element (FE) method. The interface decohesion is described using a traction-separation quadratic failure criterion along with a mixed-mode displacement formulation for the interface fracture event. Reflowed Sn-4Ag-0.5Cu (SAC405) solder ba

Recognizing Human Emotional States by Facial Expression Analysis for Humanoid Head amir-Iii
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we reviewed the existing established methods of facial expression analysis and their limitations in applications. Then we proposed a system for our own robot head AMIR-III. The research used Eigenface method utilizing Principal Component Analysis and Neural Network classifier for emotion recognition from static image frame taken from

Fruit Seeds and Peels – from Byproducts to Potentially Commercial Antioxidants
Research Output | Dar Al-hikmah Library | IIUM Only

The aim of this study was to evaluate seeds of guava, papaya and mango for their antioxidant levels and activities (i.e. primary and secondary); and compared antioxidant levels and activities in pulps and peels of two species of dragon fruits, Hylocereus undatus (white dragon fruit) and Hylocereus polyrhizus (red dragon fruit) in order to investiga

Cold and Hot Region Detectability and Image Quality Enhancement in Tc99m Spect by Reduction of Scattered Gamma Photons Prior to Detectio
Research Output | Dar Al-hikmah Library | IIUM Only

Introduction: Single Photon Emission Computed Tomography (SPECT) inherits a serious problem of scattered gamma photons emanating from the object to be scanned. It is well recognised that, presence of scattered gamma photons in SPECT projection data, degrade the image quality and limit the accuracy in quantification of radioactivity distribution. Th

Tomato Leaves Methanol Extract Posses anti-Inflammatory Activity via Inhibition of Lipopolysacharide (Lps)-induced Prostaglandin (Pge2)
Research Output | Dar Al-hikmah Library | IIUM Only

Recently, the leaves of tomato plant that contained several active compound including alkaloid, steroid and flavanoid has been used for treatment of variety of diseases included anticancer, anti-oxidant and anti-gout. Although a number of pharmacological properties have already been demonstrated, the anti-inflammatory effect of tomato leaves action

Lipid Peroxidation in Chronic Cerebral Hypoperfusion- Induced Neurodegeneration in Rats
Research Output | Dar Al-hikmah Library | IIUM Only

Introduction: Reduced cerebral blood fl ow is associated with neurodegenerative disorders and dementia, in particular. Experimental evidence has demonstrated the initiating role of chronic cerebral hypoperfusion in neuronal damage to the hippocampus, the cerebral cortex, the white matter areas and the visual system. Permanent, bilateral occlusion o

Implementation of Sarg04 Decoy State Quantum Key Distribution
Research Output | Dar Al-hikmah Library | IIUM Only

The experiment of decoy state QKD has been reported using commercial QKD system based on a standard bi-directional ‘Plug & Play’ set-up. By making simple modifications to a commercial quantum key distribution system, decoy state QKD allows us to achieve much better performance than QKD system without decoy state in terms of key generation r

2d Image Reconstruction of Radar Indera
Research Output | Dar Al-hikmah Library | IIUM Only

INDERA is the first Indonesian maritime radar that works using the frequency modulated continuous wave (FMCW) technology. In the surveillance mode INDERA continuously transmits modulated electromagnetic waves to detect targets in the surrounding area. Since the transmitted signal is a continuous wave, INDERA needs only a very small power to transmi

Optimizing the pre-Treatment of Kenaf Bast
Research Output | Dar Al-hikmah Library | IIUM Only

Kenaf (Hibiscus cannabinus) is a warm season annual fiber crop which is found to be the best alternative plant to substitute the raw material for lactic acid production due to its short period of harvest time and process high quality cellulose. It is a lignocellulosic material which is naturally resistant to breakdown to its structural sugars that
